No.736,741 Claims priority, applicationA Sweden June 5, 1957 s claims. (cl.ns1-ss) This invention relates to the wrapping of cigar bunches and 1tis an object of the invention-to make provisions for pasting the wrappercompletely, or substantially completely, without unduly extending thepath of travel of the Wrapper carrier over means for transferring anadhesive to the wrapper supported by said carrier.

Another objectl of my invention consists in the provision of means forsupplying the wrapper, supported by said carrier, with an adhesivebefore reaching the conventional wrapping mechanism and without anytendency of wrinkling, damaging and displacing the wrapper whensupported by said carrier.

Still another object of my invention consists in the provision of amethod and means for pasting the wrapper stepwise to cover the wrapperwith complementary stripes or zones of an adhesive on minimizing thespace required for that purpose.

Still another object of the invention consists in the provision of meansenabling the use of different grades of adhesive for pasting differentportions of the wrapper.

Still another object of the invention consists in the provision ofseparate wrapper pasting apparatus which can be replaced or cut out ofoperation if desired.

Still another object of the invention consists in the provision of amethod and means for pasting the wrapper by consecutive steps betweenwhich the Wrapper is subjected to a suction effect.

A further object of the invention consists in the provision of meansespecially well adapted for'applying a long, narrow and distinct stripeof adhesive to a longitudinal edge portion of the wrapper.

With these and other objects, in view, the invention consists in certainconstructions and combinations of parts which will be hereinafter fullydescribed and set forth in the appended claims.

In the drawing:

Figure 1 is an elevational view of the portion of a cigar machineequipped with means embodying the invention;

y Figure 2 is an elevational view, partly in section, taken on the linelI-II of Figure 1;.

'Figure 3 is a plan view of. a mechanism embodying ther inventioninwhich the wrapper'carrier and its operating mechanism are indicated,Aby full lines infa .rst paste receiving position and by chain-dottedlines in a second or subsequent paste receiving position; and

Figure 4 is a plan view showing means for controlling the wrappercarrier when moving past the first paste receiving position to thesecond paste receiving position.

Referring to the drawing, the wrapper carrier comprises a suction head 1secured to a hollow spindle 6, the hollow spindle 6 in turn beingrotatably mounted in the free end of a hollow arm 2. The suction head 1,

the hollow spindle 6 and the hollow arm 2 communicate with each otherinteriorlyl thereof. The arm 2 is connected by a pivot 4 to anotherhollow arm 3 and communicates interiorly therewith. The arm 3 is securedl 2,939,463 Patented June '7,V 1960 to a hollow vertical spindle 5 whichis rotatablygmountedv in a hollow post 48 and communicates interiorlywith said arm 3 and with a suction pump such as is shown in my U.S.Patent No. 2,379,575. To the carrier spindle 6 is secured an arm 7 whichcarries a roller 8 inserted in a groove 9 in a plate 11 secured yto themachine frame 10. The spindle 6 carries a roller 12 which is inserted ina groove 13 in a plateV 14 secured to the frameltl.

To the spindle 5 is secured a `toothed segment 15 which'. meshes with arack bar 16 which is slidablyV mounted. in a rectilinear guide-way 17fixed to the machine frame.. The rack bar 16 is by a pin 18 pivotallyconnected to` one end of a rod 19. The other end of the rod 19 is4 by apin 20 pivotally connected to one arm 21 of 'a'' bell crank leversecured to a rocking shaft 22 rotatably mounted in the machine frame.The other varm 23 of the bell crank lever carries a 'roller 24 which isinsertedl in a curved groove 25 in a face cam 26 secured to the.

means may be of any iwell known construction, such as shown in myPatents Nos. 2,267,648 and 2,539,034, respectively.

'I'he wrapper is transferred from the cutting bed 28 lto, the wrappingmechanism 30 by the suction head 1 and' the suction head is guided bythe groove 13 so that itV will move in a deiinite curved pathsimultaneously as it is controlled by the guide groove 9 so as to berotated about the center of its spindle 6 in a definite mannersimultaneously as the suction effect in the carrier is controlled byconventional means such as that shown 4in my Patent No. 2,379,575.

Between the cutting bed 28 and thewrapping mecha-- nism 30 is disposed areplaceable pasting apparatus 31 which comprises a rigidpastetransferring arm 33 which is adapted to move up and down in a pastecontainer 32. The arm 33 has a relatively long horizontally projectingend 34 bent angularly to conform with the contour of a longitudinal edgeof the suction head -1. The arm 33 is secured to a vertical ro'd 35which is slidably mounted in a bracket 36 xed toV a channel iron 37rigidly mounted on the machine frame 10. At'its bottom end the yrod 35is by a pin 38 pivotally connected to the upper end of another rod 39the bottom end of` which is, by a pin 40, pivotally connected to an arm41 secured to the rocking shaft 22. The arm 41 carries a follower 42inserted in the groove 43 of a face cam 44 secured to the drive shaft27. The paste supplying apparatus 29 disposed on thevfurther side of thewrappingl mechanismA 30 is of `substantially the 'same construe-ftion/as the paste'supplying apparatus 31. It has apaste container 45 anda paste supplying arm 46 which is secured to a vertical rod 47 operatedby a face cam (not shown) which is secured to the shaft 27 and issimilar to the face cam 44 but displaced angularly relative to thelatter.

During each cycle of operation of the machine the suction head 1transfers a cut wrapper from the cutting bed 28 to the wrappingmechanism 30. The groove 25 of the c-am 26 has such a curvature that thesuction head 1 will during its travel towards the wrapping mechanism 30be arrested for a very short period above the pasting apparatus 31.Simultaneously the paste supplying arm 33 is elevated so that it will byits end portion 34 apply a narrow definitely shaped angular stripe ofadhesive of substantial length to' one of the edges of the wrappersupported by the carrier 1. Thereby said edge of the wrapper will bepasted practically all the way from its tuck end, at T, to apoint at adesired distance from the head end,l at S. After the short rest in thepositionM (Figure 4) above the pasting apparatus 31 the suction headwill reassume its travel in the direction towards its turning point at Ein which the head 1 supports the tuck end of the wrapper in a positionabove the wrapping mechanism 30 so that said tuck end will be accessibleto thel `conventional tucking needle, e.g. as shown in U.S. Patent No.2,754,481 adapted to catch and move said tuck end down against the cigarbunch enclosed in the Wrapping when said mechanism starts its operation.Simultaneously as the tuck needle applies the tuck end of the wrapper tothe tuck end of the bunch the 'paste supplyin'g arm 46 is elevated andapplies to one edge of the Wrapperra relatively thin and short stripe ofadhesive which will form a continuation of the relatively long' andnarrow adhesive stripe primarily applied by the `arm 33 and extends onto the flag or head end S of the Wrapper. Thereby the wrapper has beenprovided with a narrow and distinct adhesive stripe extendingcontinuously or stepwise, all along the wrapper or at leastapproximately from one end of the wrapper to its other end and thisresult will be obtained without extending the path of travel of thesuction head and increasing the/space, without any appreciableprolongation of the operating cycle and without the use of any largepaste applying member'. The paste supplying 31 might, if desired, be cutout of operation, eg. b'y removing its paste transfering arm 33. Thepasting apparatus 29 and 31 can hold paste of different grades ifdesired.

, It will be understood that I do not care to limit the scope of theinvention to any particular form ofthe cigar and wrapper. Thus the termshead end and tuck end as used hereinbefore are merely illustrative andnot' intended to denote any particular form or use.
